Polarization Controllers and Polarization Scramblers

Control polarization the precise way

Polarization-dependent effects often have undesirable effects in fiber-optic systems, such as polarization-dependent losses (PDL) in components and devices or the amplifier’s polarization dependence in EDFAs. You can control the polarization in two ways:

With “scrambling”, the polarization state of the light with high frequency changes. In other words, the light is more or less depolarized

Use polarization controllers if you would like a specific, fixed polarization state.
